Key Parameters

Substitute Part Grouping Explanation

Substitution of the SLR-343PG3F is determined by alignment of the following critical parameters:

Optical Characteristics: Color (Green), lens transparency (Diffused), and peak wavelength (555nm) establish the visual and functional output of the LED. Substitute parts must maintain these specifications to preserve circuit behavior and user interface consistency.

Electrical Specifications: Forward voltage (2.1V typical) and test current (10mA) define the operating point within the circuit. Substitute parts must operate within these electrical parameters to ensure compatibility with existing current-limiting resistor networks and power supply designs.

Mechanical Compatibility: Mounting type (Through Hole), package style (Radial, T-1), lens size (3.10mm diameter), and maximum height (5.60mm) determine physical fit within printed circuit board layouts and mechanical assemblies. These parameters are non-negotiable for direct substitution without board redesign.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status establish the environmental and regulatory framework. Substitute parts must maintain equivalent compliance certifications.

The RLI-343P8G3F from Rohm Semiconductor is identified as a manufacturer-recommended substitute based on functional equivalence within the LED indication category.
